FLEXIBLE DRAW-BAR FOR TRACTION-ENGINES.

To all whom t may concern: n

Be it known that we, CHARLES EDWARDS and HENRY H. J UNKiN, 'citizens of the United States, residing at Drayton, in the county of Pembina and State of North Dakota, have invented certain new' and use ful Improvements in Flexible Draw-Bars for Traction-Engines; and We do declare the following to be .a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

This Iinvention relates to farming machinery and consists essentially in an attachment or drag which is adapted to be removably, adjustably and iexibly attached to a traction engine or-other draft appliances.

The principal object of the invention is in the provision of a device of the character described which is composed of two alining sections supported upon Wheels, one sect-ion of which is hinged or otherwise movably connected to a central yoke or frame to permit the same to automatically adjust itself vertically, said yoke and sections being flexibly attached to the traction engine or draft appliance, whereby the land operating devices carried by and movably attached to the hars of the sections are adapted to adjust themselves over uneven ground.

A further object of the invention is in the yprovision of means for adjusting the outer, wheels of the device, whereby the length of the same can be properly adjusted in respect to the land operating implements.

With these and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more :fully dcscribed and claimed.

from; Fig. 7 is a detail perspective view showing a section ot' the central frame to which the movable bar ot the device is a? tached; Fig. 8 is a transverse scction'of the central frame showing a portion of the movable bar and the manner in which the same is attached to the traine; Fig. t) is a trans-- versc section of one of thc bars and a portion of the stub axle located therein showing` the' means whereby the latter is properly adjusted; Fig. 10 is a top plan view of a modification o't' the invention; Fig. ll is a perspective view showing the stub axle sccured to one end ot the bars with reference to Fig. l0.

In the illustrative embodiment oi" the invention, l represents a traction engine of conventional design to which the invention is adapted to be conveniently, detachably and adiustably secured, although any other torni of draft mechanism may he employed in carrying out the invention.

The invention primarily consists ot' a drag in the form of two longitudinal bars 2 and 3 connected by a centrally disposed rectangular shaped yoke or frame 4, the letterheing provided with bearings 5 within which is mounted a shaft 6 carrying a wheel 7.

Projecting at right angles from one side of the yoke or frame 4 and rigidly secured thereto is a bar 2 to the outer end of which is adjustably secured a wheel 8 as clearly shown. To the opposite side of the yoke or frame l and hingedly attached thereto is the bar 3 which is in alinement with the bar 2 and to the outer endet' said bar is adjustably secured a wheel 9.

i The bars Q and 3 of the device are U- shaped in cross section as clearly shown in the drawings to render strength and lightness to the same and further for the purposes now to be described. l Q

The stub axles l() upon which the wheels S and t) are mounted are provided with cX- tensions ll which are slidably located within the outer ends ot the bars 2 and 3, said extensions being held in an adjusted posi` lion in respect to the bars by binding `screws l2 whereby the wheels can be pi'operly se clevis 15 which is adapted 'tobe adjustably secured along a bar 16 provided with a series of openings 17 said bar being rigidly atached to the rear end of the traction engine. Also attached to the clevis 15 are the ends of two chains 17 which lead-to and are secured'to the bars 2 and 3, whereby the entire device is flexibly attached to said engine. By the employment of the two eyes 13 secured to the opposite ends of the trame or yoke 1, the device may be reversed when desired and likewise attached 'to the traction engine. u,

Adjustably secured along the length of the bars 2 and 3 are a plurality of land op-I erating devices 18 which in the present form are shown as rakes for contact with the ground but. it is evident that any suitable land operating device or machine maybe substituted therein such as disks, drills, h arrows or other cultivators or a combination of the same. The land operating devices 18 are hingedly secured to the bars 2 and 3 by extensions 19 and are adjustable upon the same by the employment of clips 20.

In Figs. 10 and 11- a modification of the invention is shown which carries out the same principle of the invention but is some what diierently constructed, the same consisting of a rectangular shaped yoke 21 substantially the same construction as that shown in Fig. 4. AS shown rigidly projecting from one side of the yoke 21 isa plate 22 and adjustably secured upon said plate is a bar 23 by means of clips4 24 and likewise adjustably secured to thel outer end of said bar is a stub axle 25 by-means of/clips 26. To the opposite side of the yo-ke or frame 21 are secured two lugs 27 between which are pivoted the projecting end of the bar 28 the latter being adjustable along the length of the inner end of the' bar 29 by clips 30, and to the outer end of said bar 29 is adjustably secured a stub axle 31 by means otclips 32.

The device constructed as last described is attached in a like manner to the traction engine and the bars 23 and 29 are preferably constructed of hard wood` but it is evfij,

dent, however, that the saniecouldfbe o metal without departing from the nature' of the invention.

' By the construction as herein shown and described and the particular manner of attaching the same to a traction engine or other draft appliance it is evidentthat thc land operating devices will be automatically adjustable upon the surface of the ground at an even height therefrom, and further the construction of the device is particularly adapted for making a turn with the traction engine. Itis also to be desired that the land operating implements. when drawn along the surface of the ground will not crowd upon one another notwithstanding the direction in which the tractiond engine is traveling.

By the em loyment of the central lwheel 7 carried by t e frame or yoke 4 the use of long bars either metal or wood is dispensed with and further that the various parts of thedevice may be readily and easily taken apart or changed in width.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention willv be'readily understood without requiring a more extended explanation. 'Various changes in the form, proportion and the minor details of construction may be resorted to-witl1out departing from the principle or sacrificing. any of' the advantages ef the claimed invention.

Having particularly described our invention, what we claim is In a device of the character described, the combination with a centrally disposed yoke, of a wheel mounted therein, a bar rigidly secured to and projecting at right angles from v1one side of said yoke, outwardly disposed lugs projecting yfrom the opposite side of said yoke, a bar one end of which is pivoted to said lugs, whereby the last named bar is adapted to automatically adjust itself vertically, said bars being -U-shaped in cross section and in alinement with one another, stub .axles having projections adapted for sliding engagement with the outer portions of said bars, means carried by said bars for securing said projections in an adjusted p0- sition in respect to the outer ends of the bars, wheels mounted upon said stub axles, means for securing land treating devices, said means adjustable along the length of said bars between the wheels carried by the youter ends of the bars, and vflexible means leading from the yoke and also diagonally from both beams with their outer ends se- .cured to a clevis, the latter being adapted tftobe adjusted to the rearend .of ajtraction engine or other draft appliance, whereby the device is adapted to ride over the ground .and evenly support land operating devices.

Iii-testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
